So is the sleeper ammo an issue when you're fighting a boss? It deals a lot of damage, but not enough ammo to feel satisfied with the amount of health that is taken off a boss. I may have found a temporary fix. I found that 1 rocket = 7 sleeper ammo. Which means when fighting a boss, I can shoot all my rockets at him except one, switch to sleeper and have max ammo. Then switch back heavy synth, and do it all over again. Bosses fall so fast!! Let me know what you guys think?
